We study the fixed point for a non-linear transformation in the set of Hausdorffmoment sequences, defined by the formula: T ((an))n = 1/(a0+�E �E �E+an).We determine the corresponding measure�E, which has an increasing and convex density on ]0, 1[, and we study some analytic functions related to it. TheMellin transform F of �E extends to ameromorphic function in the whole complex plane. It can be characterized in analogy with the Gamma function as the unique log-convex function on ].1…

On an Iteration Leading to a q-Analogue of the Digamma Function
We show that the q-Digamma function ψq for 0<q<1 appears in an iteration studied by Berg and Durán. This is connected with the determination of the probability measure νq on the unit interval with
On Markov Moment Problem and Related Results
TLDR
New results and theorems on the vector-valued Markov moment problem are proved by means of polynomial approximation on unbounded subsets, also applying an extension of the positive linear operators’ result.
From Hahn–Banach Type Theorems to the Markov Moment Problem, Sandwich Theorems and Further Applications
The aim of this review paper is to recall known solutions for two Markov moment problems, which can be formulated as Hahn–Banach extension theorems, in order to emphasize their relationship with the

Abstract Giving necessary and sufficient conditions for the existence of solutions of truncated and full classical Markov moment problems in terms of the given (or measured) moments, in Lp,μ (S) (1 ≤
Moment problems and orthogonal polynomials
In 1894 Thomas Jan Stieltjes (1856-1894) published an extremely influential paper: Recherches sur les fractions continues, Ann. Fac. Sci. Toulouse, 8, 1–122; 9, 5–47. He introduced what is now known
Moment Problems on Bounded and Unbounded Domains
Using approximation results, we characterize the existence of the solution for a two-dimensional moment problem in the first quadrant, in terms of quadratic forms, similar to the one-dimensional
On the Moment Problem and Related Problems
Firstly, we recall the classical moment problem and some basic results related to it. By its formulation, this is an inverse problem: being given a sequence (yj)j∈ℕn  of real numbers and a closed
